Prior to testing of compounds, cells were plated at 10,000 cells/well in clear bottom 384-well black plate, and incubated overnight at 37C. with 5% CO2. On the day of experiment, culture media was removed, and replaced with assay buffer HBSS (Hanks' Balanced Salt Solution) with 20 mM HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) and 0.1% BSA (bovine serum albumin) BSA containing calcium 5 dye (Molecular Devices) and 2.5 mM probenecid. After 1 hour incubation at 37C., 5% CO2 for 60 min, cells were pre-incubated with compounds for 30 minutes.FLIPR Assay: Compounds were tested for their ability to inhibit C5a-mediated calcium mobilization using a stable cell line over expressing the human C5aR & the Galpha 15 protein on the FLIPR (Fluorescent Imaging Plate Reader) Tetra system.

On the day of experiment, culture media was removed, and replaced with assay buffer HBSS (Hanks' Balanced Salt Solution) with 20 mM HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) and 0.1% BSA (bovine serum albumin) BSA containing calcium 5 dye (Molecular Devices) and 2.5 mM probenecid. After 1 hour incubation at 37C., 5% CO2 for 60 min, cells were pre-incubated with compounds for 30 minutes.
FLIPR Assay: Compounds were tested for their ability to inhibit C5a-mediated calcium mobilization using a stable cell line over expressing the human C5aR & the Galpha 15 protein on the FLIPR (Fluorescent Imaging Plate Reader) Tetra system.
